IMPROVEMENT lN ROPE-SPINNING MACHINERY.

Specification forming part of Letters Patent N0. 218.797, dated August19, 1879 application filed June 25, 1879.

To all whom it may concern:

Be it known that I, JosEPH O. TODD, of Paterson, in the county ofPassaic and State of New Jersey, have invented a new and usefulImprovement in Rope- Spinning Machinery, which improvement is fullydescribed in the following specification.

My invention relates to that class of devices which are applied torope-spinning machinery for automatically regulating the size of thesliver or yarn.

The invention will first be described in connection with the drawings,and then pointed out in the claims.

I am aware that a ratchet feed operated by two pawls has been connectedwith the condensing-rolls through which the sliver passes;

' but such a device produces but a single and Fig. 1. Fig. 3 is a planof the regulatingrollervand its tipping frame. Fig. 4 is a plan of thedriving-shaft; and Fig. 5 is an enlarged view of amodification, showingthe frictiondriver as governed by a trumpet-guide.

In Fig. 1 the nearer frame of the machine is removed to show theconstruction more clearly.

A A are the side bars of the frame; B B, the post, and G (J thecross-ties. D is the driving-shaft of the machine. E E are the fast andloose pulleys on the same. F is the pulley for driving thecalender-rollsL, and G is the pulley for operating the friction-driver. H is thefeeding-apron, driven by shaft I, and feeding the sliver s, through'theconductor K, to the calender-rolls L.

From the calender-rolls L the twisted yarn or strand t(shown in Fig. 5)passes through the hole M in the flier O and onto the bobbin N, in theusual manner.

The end of the flier nearest the rolls L is supported by a standard, Q,and its outer end is carried by a standard. Q, and provided with apulley, P, to which motion is imparted in the usual way.

My invention having no connection with any other parts of the machinealready in common use, no references are made thereto.

My improvement embraces the parts involved in transmitting the motionfromthe main shaft D to the feed shaft I,'and which are'constructed asfollows: Between the driving and feed shafts I locate an uprightshaft,(1, provided with a disk, I), and pulley c, the former serving toreceive the motion through my friction-driver, and the latter totransmit it to the feed-shaft I.

The shaft a being vertical, and the feedshaft I revolving horizontally,an intermediate shaft, d, is provided to change the direction of themotion by means of a twist-belt, e; or suitable gearing may be employed.

The disk 1) receives its motion from a friction-driver, j, which issecured to arbort' hung in a tipping or swing frame, j.

The arbor is shown in Figs. 1 to 3, provided with a pulley, g, whichreceives a cord or belt,

h, from the pulley G on the main shaft, and

the arbor and driver f are thus revolved at a uniform rate of speed.

The roller is shown as of convex outline at its point of contact withthe disk, underneath which it is supported by frame j, the arbor z beingradial to the shaft a.

From this arrangement it is evident that if the frame j be tipped out ofa horizontal position the point of contact between the driver and thedisk will be changed, and the motion imparted to the disk will be variedin its rate of speed.

The disk and its vertical shaft are so conn ected that its weightpresses the disk constantly against the convex surface of thedrivingroller f, and, the driver being made of leather, rubber, or othersuitable material, the motion is transmitted at the desired rate ofspeed to the feed-shaft I.

To tip the frame j automatically, a connection is required to thecalender-rolls L, so that as the sliver deviates from the proper orstandard size the feed may be varied to correct the deviation. This maybe done by a connection to the calender-rolls through which the sliverpasses, or by providing a trumpet-guide, as shown in Fig. 5, to operatethe frame j as the sliver varies in size.

In Figs. 1 to 3 the frame is seen provided with a crank, 0. connected toone of its trunnions, k, and a rod, 11,1's attached to the crank, toreceive the motion from the upper calenderroll, L. The roll L is shownsupported by two levers, m, the short arms of which are pivoted close tothe roll, while the longer arms are jointed to the rod n, which thusreceives a motion much greater than that produced in the roll L by theinequality of the sliver.

So long as the sliver passes under roll L uniformly, the roll and itssupporting-lever at will remain unmoved; but any variation in the sizeof the sliver will produce a movement in the lever m and tip the framej, to which it is connected by rod n and crank 0.

The crank is so attached to the frame j that an increase in the mass ofthe sliver throws the outer end of the roller f in contact with the diskI) near its periphery, and thus reduces the speed of the feed until thesliver regains its proper size.

Should the sliver elevate the roll L an excessive amount, the feed willbe entirely arrested, as a loose pulley, w, is provided on the arbor ito come in contact with the disk when the extreme outer end of thedriving-roller f fails to reduce the speed of the feed sufficiently, theloose pulley being placed on the arbor near the. rim of the disk, andsupporting it without transmitting any motion to the feed when the framej is sufliciently tipped.

In Fig. 5 the frame j is shown controlled by a trumpet-guide, 1',through which the sliver passes to the flier, and by which thevariations in the sliver are caused to move the frame 9' as desired.

A lever, u, is hinged to the posts of the frame by fulcrum u, so thatits upper end carries the trumpet-guide r, and its lower end actuates arod, r, connected to crank o. The lever being vertical, the crank o issecured to the trunnion k in a vertical position, and the movements ofthe lever u operate the frame j in the same manner as those of thelevers m.

When thus arranged, the arbor i would be parallel with the side frames,A, and would require to be driven by some other means than the pulley g,as by a universal-joint coupling, q, connected in any suitable mannerwith the main shaft D.

From the above description it will be seen that the operation of thefriction-driver is the same, however it may be connected to the sliverso as to act automatically, and I do not therefore limit myself to thesole use of the means described for making such connection.

Both the trumpet-guide and calender-rolls are intended to be adjustable,and arranged to pass a larger or smaller sliver, as may be desired, andthe connections between them and the frame j may be made adjustable forthe same purpose in any desired manner.

I do not consider it material to the operation of my invention how thefriction-driver receives a uniform rate of motion from the main shaft D,nor that the roller f should be the driving agent in the frictionalcombination, as the uniform rate of motion might be imparted first tothe disk I), and the variable motion transmitted by the roller f to thefeedshaft 1, if preferred.

This feed-shaft I, which is the agent actuated by my improved regulator,may be employed to drive any kind of feeding-apron constructed to carrythe fibers into the machine, and I do not therefore limit myself to anyspecial construction for the said apron.

Having thus shown the essential parts of my invention to be the disk band frictionroller f, automatically operated by the sliver, I claim thesame, as follows:

1. The combination of the feed-apron H, the calender-rolls L ortrumpet-guide v, with the disk b, the frame j, the friction-roller f,and connecting and operating mechanism, substantially as described,whereby the feed is regulated according to the variations in the sliver,as set forth.

2. The combination of the friction-roller f, the loose pulley w, thearbor i, and combining and operating mechanism, substantially asdescribed, and for the purpose set forth.

In testimony that I claim the foregoing as my own I hereto subscribe myname in the presence of two witnesses.

J. O. TODD.
